I have a Tomcat cluster with mod_jk and another one with mod_proxy_http, and I'm quite happy with both. Just in case somebody is interested, this guy wrote a blog post about configuring apache with mod_proxy_http:
http://www.darkcoding.net/software/goodbye-mod_jk-hello-mod_proxy/ Although he says goodbye mod_jk, hello mod_proxy, he doesn't really justify why...
